https://www.homebuiltairplanes.com/forums/threads/ch750.31579/invalid@example.com (ddsrph)ddsrphI am interested in building a CH750. Mainly because I have a Lycoming 0235 C2C with 890 hours since new. If I was a little younger I would have started yesterday but not sure if at age 70 with an excellent RV3 if this is such a good idea. Any CH 750 builders out there with any advice on how big of a project this is. I may just sell my engine and spent the time flying the RV3. It was my first and only tailwheel airplane and I have flown in about 350 hours so far. It also has a 0235 and...

Has anyone seen a dual brake lever for mechanical brakes, that would be stick mounted. The idea would be that the handles would be close enough together to use as one handle normally, but could be activated separately if differential braking was needed. I can probably cobble something up, but if there's an off-the-shelf item, I'll start with that since I'll probably need two of them.

Can anyone make a recommendation?]]>16Stall WarningFri, 05 Jun 2020 03:13:57 +0000https://www.homebuiltairplanes.com/forums/threads/stall-warning.32644/

I have seen a number of propeller decals (of lessor quality) that simply self destruct at the first hint of moisture. See below:

Not sure, but these appear to be paper backed. And their lifespan is short. This self destruction occurs on many planes with this prop decal.

Decals have been ordered from AeroGraphics for my prop. These people are the Gold Standard in aviation decals, and they...

And is there a difference if this is installed in a C-310, or an RV-8?]]>2MystiqueFri, 29 May 2020 13:45:10 +0000https://www.homebuiltairplanes.com/forums/threads/mystique.17884/

the hub and prop flanges using the same type construction. The folding

I've got a set of ribs for a tapered wing that I'd like to print out on a single sheet. But I haven't found an easy way to overlay the parts on the sheet in an orderly manner - other than by eye. In my 2D CAD program this is easy as I can set an origin and 'snap' the parts into position relative to each other and then move the group.

The second half of this problem is that I'd also like to only...

The concept involves big spacing between the ribs/members. Few members are around 3.5m apart between. I.e.a round 3.5meters of empty space is planned to be covered with fabric. the fabric after heating will be in tension. All frame members are made to withstand all the stress forces.

The question is if the fabric...
